The international congress on architectural envelopes Special issue-2018 / 1st Edition Nieuw

With this new edition we continue the collaboration with our funding member Tecnalia and the International Congress on Architectural Envelopes (www.icae2018.eu), which they organise every 3 years in San Sebastian (Basque Country, Spain). The eleven articles found in this new issue were carefully selected from 50 abstracts that will be presented during the scientific section of the congress. The final selected papers were subjected to the regular double-blind review process of the journal. With this selection of papers, we want to give an overview of the traditional technologies that are normally discussed in the context of façades, while also making some mention of new technologies, which, some time ago, existed only in the realm of the laboratory but which have begun to appear in real buildings and construction in recent years. In fact, the main topic of the conference this year is the Envelope 4.0, and consequently the aim of the magazine. Under this title, the aim is to unify two elements: the architectural envelope, due to it being the main reason for holding the conference, and the term “Industry 4.0” as a representation of the need to improve the manufacturing, assembly, distribution, and installation processes of many of the products included in today’s envelopes in order to be competitive in the market.
